TURN-TABLE CASTING FOR LOCOMOTIVE-ENGINES.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed April 1. 1907. Serial No. 365.843.

T 0 all whom it may concern:

Be it known that I, I/VILLIAM H. \Viuon'r, citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inTurn-Table Castings for Locomotive-Engines, of which the following is aspecification.

My invention relates to in'iprovements in locomotive engines and theobject of the in- Vention is to simplify and improve the exist ing stateof the art by providing the underside of the saddle of a locomotive witha turntable casting thus insuring with safety the turning of shortcurves in the track of the road-bed when the engine is running at a highrate of speed, and consequently preventing the derailment of the wheelsand connected truck from the track and causing accidents thereby.

I accomplish these objects by the particular construction of theturn-table casting hereinbefore referred to, and the invention thereforeresides in the novel construction of said turn-table casting and theaggroupment of parts thereof in combination as will be hereinafter morefully and in detail described and then the asserted novelty will beparticularly pointed out in the claims.

I have fully and clearly illustrated the improvements in the annexeddrawings to be taken as a part of this specification, and whereinFigure 1. is an inverted view of the upper stationary section of aturn-table casting. Fig. 2 is an inverted view of the lower and movablesection of the turn-table casting, and Fig. 3 is a central sectionalview of both the stationary and movable sections and showing inconnection therewith an equalicing bar.

Referring particularly to the drawings by reference notations, Adesignates a locomotive saddle which may be cylindrical in form andwhich is rigidly secured to the underside and forward part of alocomotive, and to the underside of said saddle is rigidly secured byscrews or any suitable fastening means my improved turn-table castingwhich will be hereinafter more fully described.

B designates a turn-table casting composed of two sections, an upper andlower one, the upper one being a large stationary section C, and thelower a smaller section I), which is projected in an annular recess inthe stationary section C, and revoluble therein. The stationary sectionCis provided with a centrally formed oil reservoir E from which the oilis distributed to the bearings of the operating parts as it is receivedinto the reservoir through the medium of a tube E and slightly inclinedlubricating channel F, the tube being partly broken away, formed in thestationary section C as more clearly shown in F 3 of the drawings.

Upon the underside of the smaller section I) and formed integraltherewith are two depending semi-circular lugs or cars G G arrangedparallel with each other, and at .right angles to these, are one or moreinwardly inclined lugs G i i G, the former being arranged at suchdistance apart as to allow of one or more grooves II, II, II, which areformed equidistant apart in the space created by the arrangement of thelugs or cars G G, and these grooves are also arranged parallel with eachother and at right angles to the lugs or cars G G, the purpose of whichis to receive a round pin I the function of which is to serve as abearing or fulcrum for an equalizer-bar, said bar having also one ormore grooves j j .formed in the upper edge and centrally thereofcorresponding to those formed in the underside of the smaller andmovable section I) of the turn-table casting.

From the foregoing description taken in connection with the accompanyingdrawings the operation of my device will be obvious but may be brieflyrehearsed as follows: One end of the equalizer bar is secured to thefront driving springs of the engine and the opposite end to the forwardtruck, by which arrangement the equalizer bar is kept in position and'carries the weight of the front end of the engine, thus allowing theengine to go around curves of the track without any strain.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

1.. The combination of an equalizer-bar, with a turn-table castinghaving a stationary section provided with an annular recess a centralreservoir, and a lubricating channel leading to the reservoir.

2. The combination of an equalizer-lmr, a turn-table casting having astationary sec tion provided with an annular recess, a central reservoirand a lubricating channel leading to the reservoir for lubricating theturntable casting of a smaller and movable sectween the semi-circularlugs, grooves formed tion projected Within the stationary section bar,substantially as and for the purpose set 10 having parallelsemi-circular lugs and lugs forth. formed at right angles thereto,'parallel In testimony whereof I affix my signature, grooves formed inthe movable section and bein presence of tWo Witnesses.
